First of all, great job for coming back and realizing it's time to start up again!
I started up (again) exactly a month ago, but I decided in order to really put things into perspective, I had to know how much I gained. And of course, I started at square one, 174 lbs. Again. For the second time.
If you think that you are really able to stay on track by using your previous high as a starting point, then by all means do so! The only reason why I would suggest weighing yourself again is that you'd want to make sure you're taking in an adequate amount of calories, plus depending on your style, it might be easier to remain accountable. That's just my opinion though!
Also, eating right doesn't have to be gross at all! I find that I love a lot of Italian and Mexican foods, so I use "the good" stuff and sub out "the bad" stuff. Last night I made myself a skinny chicken parm, with chicken breast cooked in the tomato sauce to avoid oil/frying and instead of a pasta side, I had a ton of broccoli. Honestly, I haven't felt so full and satisfied from any of my previous meals like I did with that one. That's a keeper! (I also thought when I weighed in this morning, I'd show a gain due to the amount I ate, but I lost a little!)
All in all, I'm sure there are a ton of recipes out there that can make eating right taste yummy!
What kind of plan are you on? That could help with getting the right suggestions!
